ENGINEERING RESEARCH ON A PHOTOSYNTHETIC GAS EXCHANGER. PART I, EXPERIMENTAL
Abstract
The alga, Chlorella pyrenoidosa 71105, was grown as a continuously diluted culture in a 12-liter, engineering research photosynthetic gas exchanger. In this device, the algal culture surrounded a cylindrical light source having a surface area of 0.1 sq. m. Environmental conditions were kept constant by automatic control. Optimal conditions for algal growth in the gas exchanger were determined experimentally to be: 35,000 foot candles, 2.5% CO2, 0.2% packed cell volume, 0.114 hr to the minus one power dilution factor, and 39 C. Under these conditions, maximum algae yield was 0.754 gm/hr (dry wt) and maximum oxygen production was 1.25 gm/hr, or 0.03 kg per day. (Author)
